Исследование развивает направление каталитического алкоксикарбонилирования арилбромидов в жидкой фазе при атмосферном давлении. В качестве каталитической системы предложена система на основе бисацетонитрилхлорида палладия, стабилизированного в промышленной полистирольной сетке MN100. В ходе исследования было изучено влияние природы фосфинового лиганда, температуры реакционной массы, а также соотношения субстрат: катализатор на скорость и интегральную селективность процесса жидкофазного алкоксикарбонилирования пара-броманизола газообразным оксидом углерода (II). Исследована активность процесса в присутствии трифенилфосфина, трифенилфосфиноксида и 4,5-бис(дифенилфосфино)-9,9-диметилксантана. The study develops the direction of catalytic alkoxycarbonylation of aryl bromides in the liquid phase at atmospheric pressure. A catalyst based on palladium bisacetonitrile chloride stabilized in an industrial MN100 polystyrene mesh is proposed as a catalytic system. In the course of the study, the influence of the nature of the phosphine ligand, the temperature of the reaction mass was studied. The effect of the substrate-to-catalyst ratio on the rate and integral selectivity of the liquid-phase alkoxycarbonylation of para-bromanisole with carbon (II) oxide gas was also studied. The activity of the process was studied in the presence of triphenylphosphine, triphenylphosphinoxide, and in the presence of 4,5-bis (diphenylphosphino)-9,9-dimethylxanthane.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
